Design: Prospective exploratory study of infants born at <34 weeks gestational age (GA).

Setting: Two neonatal units, one in Malaysia and one in the UK (May 2019 to March 2020).

Methods: Data collected from birth until discharge and compared between units.

Results: From 100 infants included, median GA (IQR) was 31 (30-33) and mean±SD birth weight was 1549±444 g. There were more small-for-gestational age infants in Malaysian unit: 12/50 (24%) vs UK: 3/50 (6%), p=0.012 and more morbidities. More Malaysian infants received breast milk (Malaysia: 49 (98%) vs UK: 38 (76%), p=0.001), fortified breast milk (Malaysia: 43 (86%) vs UK: 13 (26%), p<0.001) and exclusive breast milk at discharge (Malaysia: 26 (52%) vs UK: 16 (32%), p=0.043). There was higher parenteral nutrition use among Malaysian infants (40/50 (80%)) vs UK (19/50 (38%)) (p<0.001) with higher protein intake (mean±SD Malaysia: 3.0±0.5 vs UK: 2.7±0.6 g/kg/d, p=0.004) in weeks 1-4 and smaller cumulative protein deficits (mean±SD Malaysia: 11.4±6.1 vs UK: 15.4±8.0 g/kg, p=0.006). There were no significant differences in short-term growth between units and more than half of the infants in both units had ≥1.28 changes in weight-for-age Z-score at discharge (p=0.841).

METHODS: An anonymous online survey among paediatricians and neonatologists from Bangladesh, Indonesia, Mexico, Nigeria, Malaysia, Singapore and Taiwan was conducted from March until October 2020. The questionnaire consisted of 40 questions on the nutritional management and expected growth outcomes of LPT in and after-hospital care.

RESULTS: Healthcare professionals from low to high Human Development (HDI) countries (n = 322) and very high HDI countries (n = 169) participated in the survey. Human milk was the preferred feeding, resulting in an adequate growth of LPT (weight, length and occipitofrontal circumference), according to a majority of respondents (low to high HDI, 179/265, 68% vs. very high HDI, 73/143, 51%; p = 0.002). The expected growth outcome was higher after-hospital discharge. Less than half of healthcare professionals started enteral feeding during the 1st hour of life. Lactation difficulties, limited access to human milk fortifiers and donor human milk, especially among low to high HDI countries, were reported as major hurdles.

RESULTS: The decline in breastfeeding in the Philippines in the mid-twentieth Century associated with intensive BMS marketing via health systems and consumer advertising. As regulations tightened, the industry more aggressively promoted CMFs for older infants and young children, thereby 'marketing around' the Milk Code. It established front groups to implement political strategies intended to weaken the country's breastfeeding policy framework while also fostering a favourable image. This included lobbying government officials and international organizations, emphasising its economic importance and threats to foreign investment and trade, direct litigation against the government, messaging that framed marketing in terms of women's choice and empowerment, and forging partnerships. A resurgence in breastfeeding from the mid-1980s onwards reflected strengthening political commitment for a national breastfeeding policy framework and Milk Code, resulting in-turn, from collective actions by breastfeeding coalitions, advocates and mothers.

METHODS AND STUDY DESIGN: PubMed and Google Scholar were searched for relevant publications in English focusing on but not limited to the use of the key words stated below.

RESULTS: Studies since the 1950s of different population groups worldwide affirmed the recognition that breastmilk fatty acid compositions are highly sensitive to maternal diet. Colostrum is richer in long-chain PUFA (LC-PUFA) metabolites of both linoleic and linolenic acids than mature milk. Among these LC-PUFA, both DHA and AA are incorporated preferentially and rapidly within the cerebral cortex and the retina during the last trimester of pregnancy and postnatal 18 months. Maternal supply of DHA and AA include maternal fatty acid stores, endogenous synthesis or directly from diet. Decreasing fish intake concomitant with increased intake of meat and vegetable oil leading to decreased intake of DHA and EPA, and an increase in AA intake, have resulted in an imbalanced n-6/n-3 PUFA ratio in breastmilk.

RESEARCH AIMS: To (1) describe exploratory estimates of greenhouse gas emission factors for all infant and young child milk formula products and (2) estimate national greenhouse gas emission association with commercial milk formulas sold in selected countries in the Asia Pacific region.

METHOD: We used a secondary data analysis descriptive design incorporating a Life Cycle Assessment (LCA) concepts and methodology to estimate kg CO2 eq. emissions per kg of milk formula, using greenhouse gas emission factors for milk powder, vegetable oils, and sugars identified from a literature review. Proportions of ingredients were calculated using FAO Codex Alimentarius guidance on milk formula products. Estimates were calculated for production and processing of individual ingredients from cradle to factory gate. Annual retail sales data for 2012-2017 was sourced from Euromonitor International for six purposively selected countries; Australia, South Korea, China, Malaysia, India, Philippines.

RESULTS: Annual emissions for milk formula products ranged from 3.95-4.04 kg CO2 eq. Milk formula sold in the six countries in 2012 contributed 2,893,030 tons CO2 eq. to global greenhouse gas emissions. Aggregate emissions were highest for products (e.g., toddler formula), which dominated sales growth. Projected 2017 emissions for milk formula retailed in China alone were 4,219,052 tons CO2 eq.
